Can’t decide what new gadget to buy? The BUG is a “Wi-Fi-ready, iPhone-sized mini computer” around which you can design nearly any gadget imaginable, “no matter how strange or specialized the purpose.” Bug Labs takes care of the hardware: Available attachments include everything from a camera to a radar detector, and you can put them together “like Legos.” True, the company expects you to write the complicated software needed to run these devices. But those who “can’t code Java and AWT” can download software written by other users from the Bug website.
